This book lays out security principles and policies for the United States to adopt in a post-Cold War world. The authors encourage Americans to take account of all threats, to emphasize preventing conflicts over winning wars, to enhance every nation’s security, to favor multilateral approaches over bilateral ones, and to promote greater citizen participation in foreign policy. The entire book is available here. The book considers how to define security, the limits of force, the limits of arms races, how to prevent and resolve conflicts, the roots of conflict, and strategies for the military defense of aggression.
